Best Public Schools in Zip Code 91942

Schools in ZIP code 91942 include nine schools: seven elementary schools, one middle school and one alternative school serving K–12; eight have 2025–2026 results, while Sparrow Academy’s latest results are from 2024–2025. The area’s average results are somewhat below state figures, but schools differ substantially. The most important finding for families is that the gap between the highest- and lowest-scoring schools is about 41–46 percentage points across subjects, so the ZIP code alone does not describe a consistent academic experience.

Fletcher Hills Elementary leads elementary schools in all-grades ELA and math, with 69% and 61% proficient; La Mesa Arts Academy leads all schools in science at 55%. At the other end, Bancroft Elementary has the lowest ELA and math results, at 23% and 20%, while Kempton Street Literacy Academy has the lowest science result, at 11%. La Mesa’s science result is 44 points above Kempton’s. SchoolDigger rankings reflect this contrast: Fletcher Hills and La Mesa Arts are both at the 85th percentile, compared with the 11th for Kempton and 13th for Bancroft. JCS - Manzanita has a mixed profile: its ELA and science results are above state results, but its math result is below.

Across the same eight schools, average ELA and math results rose from 2024–2025 to 2025–2026, by 2 and 3 percentage points, respectively, bringing the group closer to state results; science also rose, but the group’s shortfall widened. SchoolDigger rankings over three years improved 5 percentile points at Highlands Elementary and 6 at Casa de Oro Elementary, while Avondale Elementary fell 4 points. For context, 2024–2025 free/reduced lunch eligibility ranged from 34% at Fletcher Hills to 93% at Bancroft; this is an observation, not an explanation for results. Size and student–teacher ratio also do not align consistently with achievement: La Mesa Arts has 1,059 students and a 20.7 ratio, while smaller JCS has 224 students and a 14.8 ratio.
